The openstack-keystone packages provide Keystone, a Python implementation of the OpenStack identity service API, which provides Identity, Token, Catalog, and Policy services. It was found that Keystone did not correctly handle revoked PKI tokens, allowing users with revoked tokens to retain access to resources they should no longer be able to access. (CVE-2013-1865) A flaw was found in the way Keystone handled tenant names in token requests. A request containing an excessively long tenant name could cause Keystone to consume a large amount of CPU and memory. With this update, the maximum HTTP request size is limited to 112k. This can be changed via the “max_request_body_size” option in “/etc/keystone/keystone.conf”. (CVE-2013-0270) Red Hat would like to thank the OpenStack project for reporting the CVE-2013-1865 issue. Upstream acknowledges Guang Yee (HP) as the original reporter of CVE-2013-1865. The CVE-2013-0270 issue was discovered by Dan Prince of Red Hat. This update also fixes various bugs in the openstack-keystone packages. All users of openstack-keystone are advised to upgrade to these updated packages, which correct these issues. After installing the updated packages, the Keystone service (openstack-keystone) will be restarted automatically.
